26650 4S2P 10,000mAh Li-on Battery Pack Build

Howdy, in this episode we'll be building a 10,000mAh 4S2P li-on battery pack together. This is using the 5000mAh 26650 batteries I picked up off Aliexpress for just $3.99 each including postage! More details below & obviously use your common sense when doing anything like this... Matt

The batteries I bought from Ali-express were these ones, directly from the factory:

https://www.aliexpress.com/item/2PCS-LiitoKala-26650-50A-5000mah-26650-Li-ion-3-7v-Rechargeable-Battery-for-Flashlight-20A/32790517311.html

Note that I bought them for $39.99 for 10. The same listings has had them for $47 and checking today (18/10/2018) is showing them as 37.95. So the price does fluctuate on these.

I have also tested and confirmed that these batteries, they are 5000mAh rated and I'll be posting a video on these shortly.

The other part you'll need is nickel wire, look up "0.15x8mm Nickel Strip" on eBay or Amazon. I paid £11 for 2M of it, however you can get it from China for a lot less (like just £3!).
